The platform lsupp'ortsaV pair of vertical plates. I3 which are' securely held in an upright position onthe platform I2 by meansvof gussets Il which are suitably connected to the plates I3.

welding. A diaphragm structure 29. is supported The clamping strips 3l 3 chamber 34. A plurality of Slat-like supports 35, laterally spaced with respect to each other, are supported on the table I8 within the pressure chamber 34, these supports serving to support a heavy object which may be disposed on the sealer applying unit I1.

A relatively stiff pressure plate 36 is disposed on top of the diaphragm 30. On top of the pressure plate a sealing pad 31 is provided. Screws 38 suitably connect the pressure plate 36, sealing pad 31, and diaphragm 30 in assembly. A fluid pressure inlet 39 extends through the table I8 to communicate with the chamber 34 so that fluid under pressure may be supplied to said chamber from a suitable source.

A sealer inlet conduit is indicated at 40. The sealer inlet conduit 40, as best shown in Figure 2, includes a bracket 4I which supports a seal 42 in position by means of screws 43. The seal 42 may be of a conventional type so that the conduit 40 extends through the table I8 while the pressure chamber 34 may remain suitably sealed. A collar 44 encircles the conduit 4l] and is suitably disposed to bear against a washer 45 embedded within the diaphragm 30. Thus, the inlet conduit 40 extends'through the table I8, through the chamber 34, the diaphragm 3G, the pressure plate 36,

and opens outwardly with respect to the sealer applying unit I1.

A sealer exhaust conduit is indicated at 46. This exhaust conduit 46, is best shown in Figures 3 and 4, and is identical to the sealer inlet conduit 40, previously described. The sealer exhaust conduit 46 includes a bracket 41 which is adapted to retain a seal 48 within the table I8 by means of screws 49. The conduit 46 includes a collar 55 which is adapted to bear against a washer I embedded within the diaphragm 3B. As indicated at 5 I both the inlet conduit 4I) and the exhaust conduit 46 are in communication with suitable openings provided in the sealing pad 31.

Both the inlet conduit 40 and the exhaust ccnduit 46 are provided at their upper ends with a flange 52 which, as indicated in Figures 2 and 4, is recessed within the pressure plate 36. The collars 44 and 50 are suitably threaded to the conduits 40 and 4t so that the said conduits may be securely connected in assembly with the pressure plate 33 and the diaphragm 30. Flexing movement of the diaphragm 30 in an upward direction away from the pressure plate I8 will cause a slight amount of vertical movement of the conduits 40 and 43 relative to the table I8.

A cylinder block is shown in position on the sealer applying unit I1, the cylinder block being designated at 53. The block 53 has a lower face 54 and an upper face 55. A plurality of passages 56 extend through the block 53, opening outwardly on the sides 54 and 55 which are disposed opposite to each other. It must be understood, of course, that for the purpose of the illustration a cylinder block has been provided and that any cast or similarly cored member can be utilized where it is desired to apply a sealing fluid to the interior passages of the member.

During operation, the block 53 is placed on the sealer unit i1 so that the face 54 is seated on the sealing pad 31. The block 53 includes the interconnnected passages 5B, these passages possibly extending in laterally spaced fashion throughout the length of the block. The passages, as indicated, extend through the block and one of the passages 56 is placed into communication with the inlet conduit 40. Another passage may be placed into registry and communication, as indicated in Figuure 3, with the exhaust conduit 53. All of the other passages normally opening outwardly of the face 54 are now closed by virtue of the sealing pad 31. The cylinder 22 now may be operated in a conventional manner whereupon the table I8 is pivoted in such a manner that the face or surface 55 of the block 53 is placed into engagement with the sealing pad I6 supported on the ceiling plate I5. This is best shown schematically in Figure 3. The extensible cylinder 22 iirmly clamps the cylinder block 53 between the sealer unit I1 and the ceiling pad I6. At this point the passages 56 are, however, not yet effectively sealed and in order toy properly seal these passages during the application of sealer liquid, hydraulic or pneumatic pressure is applied to the pressure chamber 34 by means of the pressure inlet 39. This causes the diaphragm 3i! to effectively push the pressure plate 33 and the sealing pad 31 against the face 54 of the block and the block in turn has its face 55 rmly pressed against the ceiling pad I6 so that all but two of the passages and their respective openings are sealed. The passages which remain unsealed are those which are in communication with the inlet conduit 40 and the exhaust conduit 46. Sealer liquid under pressure now is delivered through the inlet conduit 40, the liquid being directed through the interconnected passages 56 and the residue escaping through the exhaust conduit 4B. The liquid sealer is now effectively disposed over the porous surfaces of the passages and upon hardening seals the same so that these passages may be eifectively utilized to transport liquids.

It can now be seen that an improved and eifective liquid sealer applying device has been shown and describedthis device fully achieving the objects of the invention. It must be understood that changes and modifications may be made which do not depart from the spirit of the invention as disclosed nor the scope thereof as defined in the appended claims.
